BOTTLE-FILLING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 648,864, dated May 1, 1900.

Serial No. 716,753. on; model.)

Application filed May 5 1899- To all whom, it may concern.-

Be it known that I, EDGAR FRIEDMAN, a citizen of the United States, residing at Dobbs Ferry, in the county .of Westehester and State of New York, have invented certain new and useful Improvements in Bottle-Filling Machines, of which the following is a specifica- To this end my invention comprises a rotating frame supporting a series of independently operated bottle racks or supports, a

supply or charging chamber having suitable communications with a liquid supply and with an air or gas pressure supply, a series of filling-heads arranged above the series of hottle racks or supports andhaving communications with the charging-chamber for the passage of compressed air or 'gas' and liquid, respectively, a series of cocks in the fillingheads having liquid and air ports controlling communication through said passages, means for automatically and successively opening and closing said cocks for supplying the bottles with air or gas pressure and with the liquid from the charging-chamber, and suitable means for engaging the bottle supports or racks independently and successively for moving them. downwardly to permit the removal and insertion of the bottles. In addition to the above-recited elements I provide a foot-lever which is suitably connected with the valve opening and closing devices and the bottle-s11pport-operating device and also with suitable mechanism. for rotating the frame stepby step to bring the bottle-supports succcssively into engagement with their oper ating device and the cocks successively into engagement with the opening and closing devices. The chargingchamber is preferably provided with a float attached to a double valve which automatically controls the supply of air or gas under pressure from the pressure-reservoir and also the exhaust of compressed airor gas from the charging-chamber into the open air, said float-valve being regulated by the level of the liquid in the charging-chamber and the level of the liquid being in turn regulated by the pressure of air or gas in said chamber.

My improved machine comprises, in addi- I of my improved bottle-filling machine,- some of the duplicated parts being omitted for clearness. Fig. 2 is a similar View of the lower part of the machine. Figs. 1 and 2 taken together represent the whole machine. Fig. 3 is a detail sectional elevation of the lower part of the machine, taken on the line 3 3 of Fig. 2, showing the operating foot-lever and means for rotating the frame and parts of the means for operating the bottle-supports and for opening the cocks. Fig. 4 is a detail plan view representing the base of the charging chamber, the cooks, and opening and closing mechanism parts being omitted. Fig. 5 is a detail elevation, partly in section, showing the double float-valve of the chargingchamber. Fig. 6 is a detail elevation of one of the double-armed operating-levers of the cooks. Fig. 7 is a detail vertical sectional view of the main supply-valve, for the liquid and compressed air or gas. Fig. 8 is a detail sectional view illustrating the ratchet mechanism for rotating the frame.. Fig. 9 is a detail plan view of part of the lever mechanism for operating the ratchet. Fig. 10 is a detail elevation of a modified form of machine adapted for filling barrels.

The machine may be constructed upon any suitable framework-such, for instance, as shown, consisting of the side standards 1 2, connected and braced by the main cross-bars 3. t and suitable strengthening tie-rods, said standards supporting the upwardly-projecting side bars 5 6. 10 is a central rotating hollow shaft or standard journaled in bear- .ings 11 12 upon cross-bars 3 and 4 and having keyed to it a bearing-collar 13 'just above the bearing 11 for supporting it vertically. The bearing-collar 13 is adjustably secured to the shaft by means of set-screw 14, and by the adjustment of collar 13 the height of shaft 10 and supported parts in the main frame may be regulated to correspond with the operating devices upon the main frame.

15 is the base-plate of the charging chamber or reservoir, which is formed with a central opening 15, into which the upper end of the hollow shaft 10 is snugly fitted, the charging-reservoir being mounted upon and supported by the shaft to rotate with it. 16 is the cylindrical glass wall of the charging chamher or reservoir, and '17 is the hemispherical dome of said chamber. The parts 15, 16, and 17 are fitted together with suitable rubber gaskets 18 to form hermetically-tight joints. Hollow posts or tie-rods 19 are threaded into the base-plate 15 and passed up through tapholes in the flange 17 of the dome 17, the dome being confined thereon by cap-nuts 19, which also tightly close the openings in the ends'of.

posts 19.

At the lower end of the hollow shaft 10 is secured a hollow valve-plug 20, formed with ports 20""20". The valve-plug 20 is adapted to rotate with the shaft in the valve-casing 21, which communicates with the beer-supply pipe 22 and the compressed-air or gas supply pipe 23. an'annular groove or port 21, insuring constant communication between the port 20 and beer-supply pipe 22, and an annular groove or port 21", insuring constant communication between the port 20 and the compressed-air or gas supply pipe 23. The valveplug 20 is of conical form, and its interior bore iscontracted at the lower end to receive a snugly fitting pipe 25, which passes centrally through the hollow shaft 10 up intothe bot- 1? -charging chamber for supplying compressed air or gas.

The pipe 22 communicates with the beersupply barrel or settling-cask, in which the beer is maintained under the proper pressure. The pipe 23 communicates with a reservoir of compressed air or gas, which is maintained at the required pressure. The beer. passes through the port 21 of casing 21 and port 20 of plug 20 up through hollow shaft 10 (around pipe 25) .into the charging chamber. The compressed air or gas passes through port 21 of casing 21 into port 20 of plug 20 and up through central pipe 25-to a point above the beer-level in the charging-chamber.

- Keyed to the hollow shaft 10 above bearing 12 is a ratchet-wheel 30, with which engages a spring pawl or click 31, jonrnaled at 32 upon an oscillating arm 33. The arm 33 is jonrnaled upon shaft 10, and its outer reduced end 33 rests in a forked lever 34, journaled upon the cross-bar 4 and formed integral withan arm 35. The lever 34 and arm 35 form a bell-crank rock-lever, which is operated by means of a pitman '36, journaled to the end of arm 35 at its upper end and to a'rock-arm 37 at its lower end, the rock-arm 37 being mounted upon a square shaft 38, which is The valve-casing 21 is formed with formed with rounded ends journaled in the side frames 1 and 2 of the machine.

40 is the operating foot-lever, which is also keyed to the square shaft 38. Every time the foot-lever 40 is depressed the shaftlO and supported parts are rotated one step, and simultaneouslywit-h this step-by-step rotation the other parts of the mechanism, hereinafter referred to, are successively thrown into operation, allof the parts being operated from the single foot-lever.

40 is a strong spring which sustains footlever 40 and connected parts normally in elevated position. Q I Keyed to the shaft-1O below the base 15 of the charging-chamber is a spider 50, and below the spider isalarger spider 51. Mounted rigidly in the radial arms of spiders 50 51 are the inclined bars 52, upon which are mounted the sliding bottle-supporting frames 53. Each of the sliding frames 53 comprises airack-bar 53 and integral guide-arms 53 53,

formed with guide-openings, through which the bar '52 extends. By this means the frames 53 slide up and down upon bars 52.

59 is a spiral spring surrounding bar 52 and engaging at its' upper end the guide-arm 53! and at its lower end a radial arm of spider 51. each sliding frame 53, and all of the frames are thereby normally supported in elevated position. v

54 is one of a series of ,bottle supports or racks, each of' which is provided with a pivoted pawl 55, adapted to engage rack-bar 53 of one of'the sliding frames 53. Each of the bottle supports 54 straddles the rack-bar of one of the sliding frames 53 and is provided with a clamp-screw 57, adapted to engage rack-bar 53 and secure the bottle-support inany desired adjusted position upon the sliding frame.

At the lower end of each of the sliding hook 58,adapted to be engaged by the mechanism for drawing the bottle-supports into lowcred position for the insertion and removal of the bottles, "as hereinafter explained.

is a rod pivoted at 61 to the foot-lever 40 and extending up to a point adjacent to the normally-elevated position of the hooks 58 of the sliding bottle-supporting frames 53.,

An independent spring 59' is provided for frames 53, upon guide-arm 53, is formed a bracket at the other for giving the lever 63 aninward spring tendency. As the series of bottle-supporting frames are rotated one .of

the hooks 58 will beengaged by hook 62, and under the downward movement of rod 60 the bottle-supporting frame so engaged will be drawn downwardly simultaneously with its tie-supporting frame is allowed by the pivoted connection with foot-lever 40, the springlever 63 yielding upon its journal-pin, and the slight movement in the rotary direction-is allowed by the springiness of rod 60 and its free movement laterally between pins 63. When' the bottle-supporting frame has been drawn to its lowest position for the removal and insertion of a bottle, the rod 60 is strained laterally' and outwardly from its normal position, and when the foot-lever 40 is released its spring 40 immediately returns it to elevated position, the hook 132 springing inwardly to release itself from hook 58 and return to normal position in readiness to engage the hook 58 of the succeeding bottle-supporting frame upon the next downward movement of foot-lever 40. The instant the hook 62 releases hook 58 the spring of the released bottlesupporting frame returns it to elevated position, as and for the purpose hereinafter explained. 1

The base 15 of the charging-reservoir is formed of a casting with a series of bottle-filling heads '70 projecting downwardly fromit. Each of the heads is formed with a liquid port or passage 71 in direct communication with the bottom of the charging-reservoir and with the filling-tube 71" and a passage 72, which is in communication with the hollow posts or tie rods 19, which secure the dome 17 to the base 15, and with a port 72 in therubber gasket 70 to place the bottle in communication with air or-gas pressure supplyof the charging-chamber, as hereinafter explained. The filling-tube 71 is of snflicient length to extend nearly to the bottom of the bottle X when the latter is in position, and the' lower end of the tube is curved outwardly slightly to facilitate its insertion in the bottle when the bottle is put in position upon the fillingsupport. bored transversely withia conical bore for the reception of conical plug75, whiehis formed with-transverse ports 7 5 and 75", adapted to open communication through the passages 71 and 72. The port 75" is arranged to open up communication in the passage 72 a little prior to the opening of passage 71 for the pn rpose of supplying compressed air or gas to the bottle a little prior to the flow of liquid thereto. The charging-heads are bored out in their lower face concentric to the fillingtubes for the reception of rubber gaskets 76, against which the heads of the bottles are pressed during the filling operation. Each of the valve-plugs 75 is provided with oppositely-extending hooked arms 78 and 79 for theengagemeniof the devices which open and close the cooks.

At the left-hand side of the machine, a

seat 98.

Each of the charging-heads is alsov shown in- Fig. 1, is a verticallyextending spring-rod 80, which is secured at its lower end to a rock-arm 81, keyed to the square shaft 38. The rod 80 extends slightly above the upper end of frame-bar 5, where it is confined between the lugs 82 and 83 .of the bracket-arm 84:. Projecting from the rod 80 is an annular finger 86, which is supported in the path of the hook-arms 78 of the cooks 75. As ,the frame is rotated the arm 86 will engage the hook of arm 78 and rotate it downwardly, the springy rod 80 (carrying arm 86) at the same time yielding laterally to the rotating movementof the. frame. This movement, which opens the cock 75, occurs during the depression of the foot-lever 40. When the foot-lever 40 is released, its spring restores the partsto normal position, the rod 80 moving upwardly out of engagement with hook 78 and springing back in its normal position in readiness to engage the hook-arm 78 of the succeeding'eock 75.

At the right-hand side of the machine, as shown in Fig. 1, a yielding rod 90, similar to'rod 80, extends vertically from the rockarm 91, to which it is secured. The rod 90 projects above the frame-bar 6' and is confined between the lugs 92 and 93 of the bracket 94L. 95 is an angular wfingerupon the rod 90, which engages the hook-arm 79 of the cock for operating the cock in reverse direction and closing the ports of the liquid and air supply after the bottle has been filled.

'At the upper gas supply pipe 25, within the charging-reservoir, is formed a valve-seat 98.

99is a pin valve rod formed with pointed ends, one of which engages with the valve- In the dome 17 of the chargingchamber is formed an air-escape port 100, having-a valve-seat 101, with which the opposite end of the pin-valve rod 99 is adapted I to engage.

is a float surrounding and vertically movable upon the air-pipe 25. The float 105 is attached to a yoke 106 by means of vertical rods 107, the yoke 106 being adjustably secured to the rod 99.

108 is a cock controlling the air-outlet 100. 110 is a pressure-gage. 111 is a cock in the compressed-air or gas supply pipe for regulating the supply of air or gas. 7

The ports 112 are drilled through the dome 17 intothe hollow posts 19 for forming com: munication between the air or gas space in the charging-chamber above the beer and the posts 19.

end of the compressed-air or The operation o-i' my improved filling'device, as illustrated in Figs. 1 to 9 of the drawings, may bebrieli y described as follows: As-

suming the machine to be in operative posi tion, with abottleX'held in filling position upon each. of the bottle-supporting frames, the foot-lever 40 will be drepressed to draw one of the bottle-supporting frames downwardly and outwardly, releasing the neck of the bottle from the gasket of the filling-head and allowing the re'moval of a'filled bottle and the placing of another bottle upon the vacated support. In placing the bottle in position the filling-tube is inserted in the --m'outh of the bottle and the bottle. placed upon the rack 54.. The foot-lever 40 is then released and its spring 40 immediately returns itto its normal elevated position,throwing the hook 62 out of engagement with the hook'58 of the bottle-supporting frame and allowing the resiliency of rod 60 and the springdevice 63 to return the hook-rod 60 to its normal position in readiness to engage'the succeeding bottle-supporting frame. At the same time the spring of the bottle-supportin g frame forces the frame upwardly to cause the neck of the bottle to be pressed firmlyagainst the rubber gasket in the filling-head. The foot-lever 40 is then again depressed, throwing down the succeeding bottle-supporting frame carrying a filled-bottle and simultaneonsly causing the rotation of the shaft 10 and supported parts and the opening of, the cock in the filling-head to the left and the cloaing of the cock-in the filling-head to the rig t. Y

The operation of the resilient rods 80 and a 90 in'opening and closing the cocks has already been explained. 4

The bottle-snpporting racks 54 are adjusted upon the rack-bars 56 in the manner explained to support the bottle of the desired size in proper; relation to the filling-head' The supply of beer in the barrel or cask, which is in communication with feed-pipe 22, is maintainedat the required pressure-to cause it to I -flow through the vertical pipe.10 into the charging-chamber. The beer will flow into the charging-chamber until the float 105 is elevated suflioiently to open the port 98 in the upper end of the compressed-air or gas supply pipe 25 and close port 100, leading, to the above the beer is flow of the beer.

open air, when air or gas underpressure will flow through pipe 23 into pipe 25 to the top of the charging-chamber until the pressure suflicient to counteract the During the operation of the machinelthe cock 108, controlling port 100, is left open. By. reason of the double pin-valve. 99, operated by float 105 and eontrollingports 98 and 101,

- the pressure of the compressed air or gas and the beer in the charging-chamber balance each other. Any tendency of the-air or gas pressure to become too great will immediately be checked by'reasonot the falling of the level,

of the beer, 'causin'g ijthe lowering of floatf 105, which immediately'wpens port 100 by moving stem 99 a way',f rom valve-seat 101 and closes port 98 bys'eatiirfg the valve-stem there- This actionis' ginstanfly followed by the reduction of pressure in the charging-chamber by reason of thetexhaust through port 100, and immediately following the reduction F of pressure the beer. rises .in the chamber to be checked by the opening of port 98 and clos ing of port 100 through the action of the double float-valve, allowing the air .or gas pressure to again accumulate and balance the beer. By this mechanism the level and pressure of the beer in the charging-chamber are maintained uniform.

In the filling of the bottles the plug of her, the beer flowing into the chargiug-chamher through pipe 10 to take theplace of the beer that has'filled the bottle. The bottle is given ample time to fill during the rotation from the cock-opening device to the cockclosing device 90,-. orone-half a revolution of the machine. In this manner the bottles are continuously filled and removed in readiness for corking.
